Stainless steel flanges can be said to be a tool that our every household will use. Flanges are also called flanges or flanges. Flanges are parts that connect pipes to pipes and are connected to pipe ends. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (wire) flanges and welding flanges.
The basic shape of the stainless steel flange is the same as that of the flat welding neck flange, that is, there is a bearing hole in the inner hole of the flange, the pipe is inserted into the bearing hole and welded, and a circle of weld seam is welded on the back of the flange. There is a gap between the stainless steel flange and the ferrule, which is prone to corrosion. If another seam is welded inside, this corrosion can be avoided. The fatigue strength of the socket flange welded on the inner and outer sides is 5% greater than that of the flat welded flange and the static strength is the same. Its inner diameter must be consistent with the inner diameter of the pipe. The socket flange is only suitable for pipes with a nominal diameter of 150 or less use. Commonly used materials for socket stainless steel flanges include: 201 304 316 304L 316.
Welded threaded stainless steel flanges are forged, and can also be formed by threaded connections or welding. It consists of a pair of threaded flanges, a gasket and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the specific pressure on the surface of the gasket reaches a certain value and then deforms, and fills the unevenness on the sealing surface to make the connection tight. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection method for pipeline construction.
The threaded stainless steel flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. In layman's terms, the function of the welded socket stainless steel flange is to fix and seal the joints of the pipe fittings. The stainless steel threaded flange connects the pipeline and maintains the sealing performance of the pipeline, which is convenient for the replacement of a certain section of pipeline, easy to disassemble and check the condition of the pipeline, and convenient for the sealing of a certain section of pipeline.
